Have you marketed your heat trap yet?

First let me explain what a heat trap is, you have this magical device when once filled with hot air never cools down, so you heat up the air to say 100F and put it where nothing can reheat it and then put it in a place at 0F and if a heat trap works, the temperature will stay inside at 100F forever. so have the people who called me a complete moron show me their heat trap. and don't tell me the earths core is a heat trap because with all the pressure down there, it has a heat source
